Scientists at Kew interested in the classification of legumes have been studying the chemistry of the Kentucky yellow-wood (Cladrastis kentukea). Evidence from DNA sequencing suggested that this species is ...

The "electronic nose," which detects odors, has a companion among emerging futuristic "e-sensing" devices intended to replace abilities that once were strictly human-and-animal-only. It is a "magnetic tongue" ...

Bone is one of nature's surprising "building materials." Pound-for-pound it's stronger than steel, tough yet resilient. Scientists at the U.S. Department of Energy's Ames Laboratory have identified the composition ...

Using a handheld molecular imaging device in combination with magnetic nanoparticles and a smartphone, a team of investigators from the Massachusetts General Hospital and Harvard Medical School has developed a fast, portable ...

You pick up a bottle of pomegranate juice at the store because you've learned that, although it costs more than most juices, it is replete with antioxidants that bring health benefits. But wait: Is the juice ...

(PhysOrg.com) -- Most proteins are shapely, but about one-third of them lack a definitive form, at least that scientists can readily observe. These intrinsically disordered proteins (IDPs) perform a host of ...

Most proteins are shapely. But about one-third of them lack a definitive form, at least that scientists can readily observe. These intrinsically disordered proteins (IDPs) perform a host of important biological ...

(PhysOrg.com) -- Metalloproteins, such as the copper-containing azurin, play a major role in catalyzing electron transfer in cellular reactions. Understanding how their structure relates to function can give ...

In a finding that overturns conventional wisdom, scientists are reporting the first discovery of the female sex hormone progesterone in a plant. Until now, scientists thought that only animals could make progesterone. ...

The Atlantic blue crab, Callinectes sapidus, long prized as a savory meal at a summer party or seafood restaurant, is a multi-million dollar source of income for those who harvest, process and market the crustacean along ...

Understanding the incredibly speedy atomic mechanisms at work when a protein transitions from one shape to another has been an elusive scientific goal for years, but an essential one for elucidating the full ...

Doctors may soon be able to quickly and accurately diagnose the cause of pneumonia-like symptoms by examining the chemicals found in a patient's urine, suggests a new study led by UC Davis biochemist Carolyn ...
